- fixed memory leaks introduced in previous revision

- removed incorrect casts of MTGCardInstance into Spell objects.
- AI Test system now allows you to put decks in ai/bakaA and ai/bakaB instead of ai/baka. This allows to let AIPlayerBaka and AIPlayerBakaB play with specific decks
- Test suite speed improvement. Improved the card name cache. Test suite now runs in 850 seconds instead of 950 on my machine.
- minor code cleanup
